I was roaming in the USA recently and I usually connect to the AT&T network but there was a moment where it said my service provider was "UMA". I called 611 and it just told me my call cannot be completed. I went to scan for networks and all it can find was UMA, not AT&T or T-Mobile. Eventually it went back to AT&T... but I'm wondering what is UMA?
when you're roaming, you'll see the name of the local network you're connecting to. in maryland, i usually connect to cellone dcs, but otherwise i connect to t_mobile. when you're connected to uma you might also see a triangle where your edge or 3g symbol is on the taskbar.

I have a Cingular Sim card, and Cingular service on my XDA II, I live in the United States (Massachusetts). It always connects to AT&T Wireless's towers because AT&T Wireless is now part of Cingular, I want to get on Cingulars towers, any ideas people?
you could set the Network Selection to Manual instead of Automatic and choose cingular......... and also set the Prefered Networks only yo cingular....
hope this help
nope, when i do manual selection i only get t-mobile and at&t wireless. =/
well it means there isn't any cingular towers near you!
there are towers next to me, it just picks up at&t wireless, not cingular.. cingular is set in the Set Networks though, but when I try to manual connect, only AT&T Wireless comes up...
Got an x10 today off ebay, unlocked after browsing this forum, by htc-code, network shows carrier on home screen, signal shows 4 bars, yet in status it says mobile network state: disconnected, this results in me not being able to get any calls at all, not even a simple balance check, the sim card is pay&go whilst I sort it out but as far as I'm concerned it isn't a data plan issue or anything like that.
Just wondered whether this is an issue anyone knows anything about or whether it's been imei blocked or whether I should just get in touch with tesco.
possibly important info:
Tesco mobile
phone was locked to orange, now unlocked
firmware 1.6
baseband 1.1.25
kernel 2.6.29-rel semc-android semc #2
signal strength -85dbm 14asu
mobile network type utms
service state in service
mobile network state disconnected
Being a pay as you go, the SIM might need activating? Ring your Telco and see what they say.
The sim came out of another phone I've been using for the past 3 years I'll give them a call later to set up a data plan anyway.
Got hold of Tesco, they couldn't solve it, imei isn't blocked or anything, tried and Orange simcard (the network it was originally on) and that works and makes calls, my other sim doesn't make or recieve calls, so it looks like it hasn't been unlocked fully. I need to get hold of htc-code and try to figure out a solution, that is, when they're online. I'll post back with an outcome.
both my x10a and my nexus1 say the same thing, mobile network state disconnected, and my phones work great. i am on wifi now, but when i turn off wifi my phone has no issues with cellular data.
your phone must not be unlocked yet or you might not have entered your apn correctly. make sure the apn is correct for your network and try again
i just turned off wifi and waited for the 3g symbol to reappear and now my mobile network state reads connected. so this indicates if you are attached to the network for data only.
i would still make sure that you manually configure your networks apn settings and then try to make a call. i think i had an issue when i had flashed to a different firmware and had not entered my carriers info.
Thanks for the reply mate, I'll try that seeing as ferraripassion/sudarshan is offline I'll let you know how it goes.
Sort of fixed, manually entering APN puts up 3g symbol and changes mobile network state to connected, even on wap internet, but I still can't make or receive calls on this sim card :/
Thought I'd check the phone on checkmend this morning, although the phone does still work on an orange sim card, checkmend says
Ever blocked UK: This item has been blocked during its lifetime by one or more UK network(s).
IMEI Currently blocked: This item is currently blocked on one or more networks. It may still work on some networks.

So, with that, does anyone have any advice on IMEI unblocking/people to contact and getting my cash back?
Write to matey boy on eBay and get money back. Because clearly, he's sold a non-working phone that's probably been nicked.
i have a mytouch 3g and i want to roam on at&t network and when i try to click at&t says that the sim card is not registered to this network.
Be nice to see this one answered. I've never worried with it until I was riding down I-40 from TN to NC today and ran into the same issue. Weird thing is, I would roam every now and then on AT&T's network, but couldn't select it to manually jump on their network.
i just want them to terminate my contract i have free roaming but it still costs them money and they send you warnings to stop your roaming if not they have to terminate the contract lol i know someone that works for tech support in sprint and she tells me she sees this often
anyone know?
Hey do anyone know if the NS can roam? The reason I ask is because where I live there's basically no t_mobile service but there is ATT service. So I was wondering is there's a way to get the phone to roam on ATT network instead of T-Mobile?
I went into setting > Network and Wireless > Mobile Network Settings and clicked network operators and ATT displayed. I clicked it and got the popup that it was "Registering with ATT" but then got the message that this sim card do not allow connection to that provider"
Also why do the bars change green to white, do they indicate something when they change colors?

the change in color indicates connectivity to google services
Yes you can but you will get your standard roaming charges.
If T-Mobile has a roaming agreement where you are and you can not access T-Mobile's native network then the NS will roam, just like any other T-Mobile phone. It is not at all different from the rest of their phones.

So when they turn Green then they're connecting to Google services and when they're white, they're not?

Well let me ask you this, I was at the mall yesterday and all of a sudden I had no bars and signal. I tried to make a call and it said something to the effect of "Mobile network unavailable...emergency calls only" Wouldn't the phone roam at this point or no?
I also went into settings > wireless and Networks > Mobile Networks a> Network Operators ...I did a search ATT popped up, Iclicked it and got the message that it was registering..then I got the message that it was unable to register with ATT. Can the phone be forced to roam and connect to another carrier?
Hello guys. After paying off the remainder of my S8's bill on sprint they unlocked it (or so they said). I then used your guide to install Samsung and at&t's firmware. From there I went to an at&t store, bought an at&t go phone sim card, installed it, activated their service and changed my number. LTE works fine, but I don't think 2g and 3g are working.
1. Under sim card status it says disconnected mobile network state. My IMS registration status is not registered either.
2. Under connections - mobile networks - network operators at&t - search for at&t microcell it says "Failed to connect to mobile network via at&t MicroCell. Try again.
3. Under connections - mobile networks - access point names it says "ATT Nextgenphone", that's all. I would of thought more options would be here. ?
According to the app open signal my phone never uses 2g or 3g.
Please let me know what I should do next. Thank you.
